Should you worry that the car next to you is stealing signal from your cell booster?

If you’re out on the road, you probably need a cell booster. Sure, the cell carriers do a pretty good job of blanketing the highways with good cell signal. But then, traffic gets worse every year. There’s no way that cell carriers can keep up with a highway covered completely in cars. Think about it… most of those cars, trucks, and SUVs are streaming, using Waze, and some are probably watching movies while they should be driving. That means it’s a dog-eat-dog world out there. There’s never going to be enough cell signal, and the vehicles with cell boosters are going to get it first.

Why? Simply put, cell phone signal boosters have a better chance of connecting to distant towers. They also have a better chance of holding on to a weak signal. That’s the kind of advantage you’re going to need to make sure you stay connected.

RV users need good service too, but are they giving an unfair advantage?

Everyone with an RV can benefit from a cell booster. It’s simple to install and gives up to 8 people in your RV good, strong cell service even when the towers are too far away for most phones. That means no more worries about the kids’ streaming movies stopping just because you take a tour through some unexplored country. It means your spouse won’t miss an important email while you’re driving, and you’ll all be safe if you need to pull over to make an emergency call.

But if you put in that booster, will the cars around you simply steal the signal, leaving you out in the cold? After all, the height of the RV means it has the best chance of getting even the weakest signals. Putting that outdoor antenna high up means it won’t be blocked by much, save for the occasional giant semi.

Does this mean that RV users could be supplying their neighbors with service while on the road? Not likely. The 45dB max power allowed by law for a cell booster in a vehicle means the signal won’t travel very far outside the RV. While the fiberglass walls of your RV won’t stop the signal from traveling out, it won’t matter. The signal just won’t go that far. It probably won’t penetrate into the next car, even if it’s just a few feet away.

Cell phone signal boosters for vehicles are all the rage. You can get single-user ones that cover just the driver’s seat, or whole-vehicle systems that will let everyone in the back of the RV stream, surf, and shop at the same time.
